The jury of nine women and three men heard that Collins, who came to fame with Channel 4's The Friday Night Project, made Ms Larke, 38, close her email, Facebook and Twitter accounts after reading her messages.

The comic, who also appeared in West End musical Rock Of Ages, made her throw away her DVD collection "on the basis she found some of the male actors in the movies to be attractive", it is alleged.

Ms Larke also told police that the comic "has a problem with people of colour", and the jury heard a recording of him accusing her of infidelities with men from ethnic minorities.

They met while Collins was still married. Ms Larke helped him move from Bristol to Kew, south-west London, in January last year before she moved in with him.

"Significantly, Mr Collins resorted to compiling a dossier in the form of a Pukka Pad notebook. The purpose of the notebook was to list every sexual experience with every one of Ms Larke's previous lovers or partners. He would ask her questions and then write it down," he said.

"She felt it was a disgusting thing to have to do and she was worried that she would lose him by doing it."

The court was played a tape recording Ms Larke made of a row between the pair at their home after they visited a pub in July last year.

Collins accused her of "fancying" a younger man they saw hugging his partner while at the pub, after she said she wanted to be embraced the same way.

In the recording, Collins accuses Ms Larke of being "very promiscuous" and having had 50 lovers.

Collins, who denies harassing his ex-partner, sat in the dock wearing his trademark beard and long hair.

He listened as Mr Shaw added that he threatened to "put her in hospital unless she shut up".

Recovering alcoholic Ms Larke tried to help the defendant get anger management therapy and sent him a link to a domestic violence course, Mr Shaw said.

On a trip to Miami in March last year, Collins grabbed his partner's hair and pulled her to the floor, pinning her down and spitting in her face, the barrister said.

She screamed so loudly that hotel staff came to see what was happening, he said.

The following May, Collins returned home from filming abroad and was "angry" that Ms Larke only managed to attend one of two Alcoholics Anonymous meetings that day, accusing her of infidelity.

"He was slapping her and she was forced to flee the flat screaming for help," Mr Shaw said.

Collins was also said to have assaulted Ms Larke in June last year, throwing a sat nav at her and pulling her hair when he arrived to collect her and she was not where he expected her to be.

Collins told detectives after his arrest that Ms Larke was the possessive one in the relationship and denied assaulting her "other than slapping her cheek to calm her when she'd been self-harming".

The court heard a police interview with Ms Larke in which she said she believed Collins was depressed and had "ridiculously low self-esteem".

He would make her wear different clothes or change her hair if he did not like it, she told officers.

When he assaulted her, his temper would "blow" and he "smacked" her in the face, she said.

Ms Larke also said that Collins attacked her in public "but nobody did anything".

She told police: "He is a nasty b*****d. A nasty horrible man.

"I was on eggshells all the time. Everything I did or said was wrong and being picked to pieces."

The TV star intentionally deprived her of sleep, telling her she had to stay awake as long as he was, otherwise she "ran the risk of him texting other women", she told the court.

Collins wrote in the sex book "Anna's Types" and listed a series of men including "men of colour, Mediterranean, older men, younger guys do it for you", she said.

Ms Larke admitted, under cross-examination by Collins's barrister, Sonia Woodley QC, that she mentioned going to PR guru Max Clifford out of "bravado".

The QC said: "You have considered Max Clifford haven't you?"

Ms Larke replied: "I very briefly considered going to Max Clifford but in my heart I knew it was right to go to court."
